Performance Prediction Models in the Superpave Mix Design System
The objectives of the Strategic Highway Research Program's (SHRP's) asphalt research program were: to extend the life or reduce the life-cycle costs of asphalt pavements; to reduce maintenance costs; and to minimize the number of premature pavement failures. An important result of this research effort is the development of performance-based asphalt binder and asphalt paving mix specifications to control three distress modes: permanent deformation; fatigue cracking; and low-temperature cracking. The SHRP-005 contract developed detailed pavement performance models to support the development of these specifications, and as an integral tool for mix design in the Superpave mix design system. This report summarizes the theoretical development, structure, and features of these performance models. Comprehensive pavement performance models were developed that predict the amount of permanent deformation and fatigue cracking (the load-related model) and the amount of low-temperature cracking (the non-load-related model) developed over time in asphalt concrete pavements constructed with paving mixes designed with the Superpave system or other mix design methods. The models employ test results from the Superpave accelerated performance tests combined with detailed environmental, structural, and traffic data to determine the optimal mix design for the given conditions, or to analyze the potential performance of field cores.
